The promises you have made will make life massively worse for your beloved Ivanka, Tiffany, Donald Jr., Eric, Barron, and your future grandchildren, who will likely be born into a planet that is practically unlivable.

We know you don’t believe the scientists on this issue, so why should you believe us?

Well, you don’t have to. But as the president-elect of our country, we are going to assume that you care about the safety and security of Americans, about our defense, military, and naval operations across the world.

According to NASA, whose scientific prowess is unrivaled and unparalleled across the globe, “two key climate change indicators — global surface temperatures and Arctic sea ice extent — have broken numerous records through the first half of 2016. Since 1880, the six-month period from January to June was also the planet’s warmest half-year on record, with an average temperature 1.3 degrees Celsius (2.4 degrees Fahrenheit) warmer than the late nineteenth century.” NASA has also confirmed that the level of carbon dioxide in the atmosphere is the highest it’s been in 650,000 years.

The science is not debatable. It is not coming from China; it is coming from the United States. If anything, ensuring that the United States and China cooperate to undertake serious action on climate is a firm but sophisticated strategy employed by the U.S.— not the other way around.

Now even if the science does not convince you, the national security case for climate action is a powerful one. The Department of Defense agrees, the Military agrees, the Navy agrees.

In July 2015, the Pentagon released a report concluding that climate change poses significant risk to U.S. national security and international security. Specifically, it refers to climate change as a “threat multiplier” that can exacerbate challenges ranging from infectious disease to terrorism. Accordingly, the Pentagon rightly incorporates climate change into virtually all aspects of its operations, including weapons testing, training troops, war planning, and joint exercises with allies.

Just months ago, U.S. military officers and national security experts offered a stark warning: the effects of climate change hinder U.S. military operations and could increase the threat of international conflict. Both retired General Anthony Zinni and retired Admiral Samuel Locklear endorsed this warning. A similar report by a panel of retired military officials stated that more frequent extreme weather is a threat to U.S. coastal military installations.

Finally, Honorable Ray Mabus, the Secretary of the Navy, asserts that, “As the climate changes, our responsibilities change. As the Arctic is becoming ice free, at least in the summer, we have a responsibility in the Arctic — for search and rescue, for helping to keep the sea-lanes open for everybody. When the sea levels rise, instability almost inevitably follows… As sea levels rise, it’s beginning to endanger our naval bases on the water.”
